I use kana / vim-textobj-user to define some custom objects user [...] for example, I use the same text object is indented, which is displayed aiand iiI want to jump text in normal mode about how ]iand[i
Vim has a bunch of built-in commands like ]m, [Metc. So I thought you meant ]i/ [ito move the cursor to the next / previous text object. If so, vim-textobj-user supports both selection and move to a text object since its first release. But it is not automatic. At the very least, you should declare which keys (e.g. ]i/ [i) should be used for commands.
But I wonder about the following sesntence:
, vaio<Esc> vai<Esc>? , / ? , vim-textobj-user API .
, nmap ]i vai<Esc>. .
